Amazon Stock Falls 13% – Mechanical Turk Being Shut Down

Amazon.com Inc. (AMZN) stock lost 13 percent of its value over the past month (as of July 5, 2026). At the same time, the company announced on July 5, 2026, that the crowdsourcing service Mechanical Turk will no longer accept new customers – a move that could signal the end of the service that launched in 2005.

Mechanical Turk Approaching Its End

Mechanical Turk, a platform for digital microtasks performed by human workers, will no longer accept new registrations as of now. The service enabled companies to outsource tasks such as image recognition, data verification, or surveys to a global crowd in exchange for payment. Amazon has not yet issued an official statement regarding the complete shutdown of the service.

Stock Decline Driven by Investment Costs

According to market observers, the 13 percent stock decline over the past month is likely linked to the company's massive capital expenditures and concerns about consumer spending patterns. Despite these concerns, Amazon continued to record double-digit growth rates in net revenues.

AWS Growing – But Meta Building Competition

Amazon Web Services (AWS), the company's cloud division, remains a growth driver. In the first quarter of 2026, AWS revenue increased 28 percent year-over-year – the strongest growth in 15 quarters. AWS is the global leader in cloud infrastructure and provides companies with computing power, storage, and artificial intelligence services.

This market dominance could come under pressure: Meta Platforms is planning to build its own cloud business to sell AI computing power. This would put Meta in direct competition with AWS, Microsoft Azure, and Google Cloud. Details about the timeline and scope of Meta's planned cloud offering are not yet known.

New AI Chips for Devices and Mobile

On July 2, 2026, Amazon's head of devices and services introduced new AI chips intended for use in home technology products and future mobile devices. The chips support Amazon's expansion of its artificial intelligence strategy, including the further development of the Alexa voice assistant and a premium service called Alexa Plus.

Indirect Stake in Anthropic

Beyond its own developments, Amazon indirectly benefits from the boom in artificial intelligence: the AI company Anthropic, in which Amazon has a stake, confidentially filed for an initial public offering in June 2026. A recent funding round valued Anthropic at 965 billion US dollars. Alphabet holds approximately 14 percent of Anthropic – a stake worth around 135 billion US dollars. Amazon's stake in Anthropic has not been disclosed.

Classification for Investors

Whether Amazon stock is a buy after the 13 percent decline depends on assessing several factors: the cloud business shows robust growth but faces new competition. High investments in AI and infrastructure burden short-term profitability but could strengthen competitive positioning in the long term. The shutdown of Mechanical Turk affects a niche service with no material revenue significance.

Investors should monitor the further development of consumer spending, the impact of capital expenditures on margins, and competitive dynamics in the cloud market. Specific price targets or valuation metrics are not currently available.
